Specification of Letters Patent.

Patented Jan. 13, 1914 Application filed larch 25,1913. Serial No. 756,815.

To all whom it mayconcem:

- this application.

Be it known that I, WILLIAM G. KEN- DALL, citizen pf the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Tops for Beceptacles, of which the following is a specification.

My invention "relates to new and useful improvements in safety caps for cans or other receptacles, particularly for containers for toilet powder and the object of my invention is to provide an improved and eflicient form of sifter cap inclosing all of the sifter mechanism and adapted for detachable application to the can or receptacle; the entire sifter as a whole, thereforebeing independent of the can construction.

More specifically this invention embodies an improvement over the structure disclosed in my copending application filed December 19, 1912, and bearing SerialNo. 737,716, the

improvement consisting in the provision of a slightly modified form of sifter' plate and in the provision of a separable spring for holding the sifter plate in position.

The chief object which I have in view in my present application. is the provision of a sifter plate so constructed that it may be made out of any suitable weight of either resilient or non-resilient metal, whereas the sifter plate described in my copending application above re erred to must be made out of resilient metal. 1

Another advantage obtained by this construction is that the spring, being formed independently of the sifter plate, may be made in any desired strength and may be readily replaced if unduly worn or broken, thus greatly increasing the efliciency of the device as a whole if the receptacle is to be constantly employed, being. refilled as its vcontents become depleted, instead of serving merely as a sales package which is to be thrown away after its contents are used.

With these and other ob ects in v1ew, my

invention will be more fully described, illustrated in the accompanymg drawing, and then specifically pointed out in the claims which are attached to and form a part of In the drawing: Figure 1 is a perspectlve view ofmy improved sifter plate applled to a conventional form of toilet powder can; Fig. 2 is a central vertical section taken longitudinally of the sliding sifter plate and showing the position of the latter Within the cap as well as the manner in which the spring holds the plate in place; Fig. 3 is a horizontal section taken through the plane of the slot in the cap looking upwardly, and showing the sifter plate in pothe can; Fig. 4 is a view similar to that shown in Fig. 3 but illustrating the position of the closure plate when powder is to be discharged from the can; Fig. 5 is a detail perspective view, upon a somewhat enlarged scale, of the sifter plate and spring employed in the cap. Corresponding and like parts are referred to in the following description andindicatjed in all the views of the drawing by the same reference characters.

The preferred embodiment of my invention, as clearly illustrated in the drawing, includes a powder can 10 of conventional type provided with an unthreaded discharge neck 11 adapted for frictional engagement by the collar or flange 12 of a cap 13, the top of which is provided with a plurality of sifter or discharge openings 14.

My invention further consistsin'the provision of a sliding sifter plate 15 mounted within the cap and adapted to control the discharge of powder therethrough, said plate being held in position by a spring 16.

More specifically, the cap 12 is provided immediately above the can engaging portion of its collar or flange with a pair 0 spaced, outstruck, vertically extending depressions forming seats 17, the purpose of which will be hereinafter explained The central portion of the top of the cap is depressed as shown and it is this depressed portion which is perforated. In order to stifi'en the top of the cap'and therefore permit the cap to be formed either of relatively sition to cut off the passage of powder from metal. 1%. CQPY ribs 18 formed in any well known manner such as by interiorly depressing portions of the cap top. That portion of the collar or flange of the cap between the can engaging portion andthe top and midway between the seats 17 is provided with a slot 19.

The sliding plate 15 comprises a substantially rectangular shaped body member provided with perforations 20 arranged to correspond with the perforations 14 of the cap and provided at one end .with an integrally formed tongue 21 which is bent into slightly oliset relation to the body of the plate and which is extended outwardly through the slot of the cap with its free end bent downwardly as shown at 22. The body portion of the plate 15 at the end opposite this tongue is provided with a downwardly extending tongue 23.

The spring 16 previously referred to is a leaf spring, the intermediate portion of which bears against the outer face of the tongue 23 and the side portions of which are bent at right angles to-the intermediate portion as at 24 but extend one upon either side beyond the tongue 23 and bear against the lower face of the sifter plate 15.

gage in the seats 17 of the cap The terminals of the spring are bent laterally and rearwardly to form arcuate spring arms 25, the free ends of which en in such a manner as to at all times hold t e spring under tension. It will therefore be apparent that the spring 16 bearing as it does against the tongue 23 tends at all times to force the sliding sifter plate to the position shown in Fig. 3 of the drawing and to thus prevent escape of powder through the perforations of the cap. brought to bear against the terminal'22 of the tongue 21 of the Sifter plate however, will force the plate inwardly against the action of the spring 16 to bring its perforations in alinement with the perforations of the cap and so permit the discharge of powder from the receptacle. as soon however, as this pressure is removed the spring will immediately return the plate {a normal position and close the discharge;

. plate in frictional out with the innor faoe of the cap to prevent any leakage between the t th --1 'm-l 0f the theseatsof plate and cap, this latter i being due to the binding of the intermediate? portion of the spring about the tongue and" 5 face of the cap, the perforations of the plate will register with the perforations of the cap. Because of this all danger of forcing the sifter plate beyond its operative position is avoided. As the spring is at all times under tension, all independent movement of the spring, sifter plate and cap is prevented, save when the sifter plate is manually moved and all rattling of the parts is therefore avoided.

It will be noted that the discharge openings or perforations of the sifter plate are somewhat greater in diameter than those of the cap to insure a. free flow of powder from the receptacle and to avoid clogging of the sifter.

Although I have illustrated and described my improved siiter plate and spring as employed with a can closure of the type set of course be understood that it may be employed with caps of a different nature and it will further be understood that I reserve the right to make various minor changes, within the scope of the appended claims, in the construction of the sifter plate and spring themselves, if desired.

Havingthus described the invention, what is claimed as new is 1. A Sifter cap for cans including a perforated top and an integral collar for attachment to the can, a' sliding plate mounted in the cap and having perforations movable into and out of aliuement with the perforations of the cap, a dowip igardly depending tongue formed on the of said plate, and a spring having a U-shape intermediate portion engagingabout the tongue on ing against the collar of the cap.

2. A sifter cap for cans including a perforated top and an integral collar adapted for attachment to a can and rovided at one 2 side with a slot, a sliding p mounted in I the cap and having perforations movable into and out of alinemeut with the perfonations of the cap, a tongue formed upon one end of the plate and extending through I the slot with its free end bent downwardly,

5 a second tongue formed on the opposite end 3 of the plate and bent downwardly, and aleaf sprmg against the outer face l of said second tongue, said spring beingbent to extend inwarfly over the plate upon either side and having its end portions rebent arouatelyr and enga I the collar.

A sitter cap forcans inclu a perfo- 1 rated top and an integral collar adapted for cap and having perforations movable into and out of alinement with the perforations 1 of the cap,

i of the plate and extending through the slot forth in my copending application, it will three sides and arcuate end portions engagj attachment to a can and provided at one side with a-slot, a sli plate mounted in the v atonguefonnedupononeend with its. free 'end bent downwardly, -a second tongue formed on the opposite end of the plate and bent. downwardly, and a leaf spring bearing against the outer face of said second tongue, said spring'being bent to extend inwardly over the plate upon either side and having its end portions rebent arcu-' ately and, engaging against the collar, said collar being provided with outstruck portions forming seatsin which the end por- 10 t'ions ofthe sprin enga e.
